26261 already, reset in_changed_variables flag for it and propagate
26262 cur_loc_changed over to the new variable. On empty var
26263 always set cur_loc_changed. Set in_changed_variables on whatever
26264 var is added to changed_variables.
26265 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
26266 Use shared_var_p. When removing loc that is equal to cur_loc,
26267 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
26268 end, don't set it to something else, just call variable_was_changed.
26269 (delete_slot_part): Use shared_var_p. When cur_loc equals to

26273 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
26274 allocated. Always create SUBREGs if simplify_subreg failed.
26275 Prefer to use cur_loc, when that fails and still in

26277 cur_loc_changed of variables which had to change cur_loc and
26278 compute elcd->cur_loc_changed if any of the subexpressions used
26279 had to change cur_loc.

26287 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
26288 first loc_chain location if NULL before. Always use just
26289 cur_loc instead of first loc_chain location. When cur_loc_changed
26290 is false, when not --enable-checking=rtl just don't emit any note.
26291 When rtl checking, compute the note and assert it is the same
26292 as previous note. Clear cur_loc_changed and in_changed_variables
26293 at the end before removing from changed_variables.
